The research objective is to index and evaluate the process plans based upon the energy consumption of the machining operations while considering machining cost and to rank or index the process plans based on energy consumption for purposes of decision support in process plan selection. The paper also discusses energy evaluation of process plans and their subsequent effectiveness in terms of overall cost associated with the utilization of effective machining parameters. The MPSEL system, which is an expert system based application, was used to develop alternative process plans. The MACH program, which is a spreadsheet based system, was used to determine the cost associated with machining. The developed process plans are compared based upon the cost associated with utilized energy and machining.</p><p>This article is available on IGI Global’s premier research database, InfoSci-Journals.

Four AM process parameters viz. Bed temperature, nozzle temperature, Infill, layer thickness are taken as input while circularity and flatness error in ABS part are taken as response. A mathematical model is developed for circularity and flatness error individually using regression technique in terms of process parameters as design variables. For the optimum search of the AM process parameter values, minimization of circularity and flatness are formulated as multi-objective, multi-variable optimization problem which is optimized using particle swarm optimization (PSO) algorithm and hence improving the geometrical accuracy of the ABS part.</p><p>This article is available on IGI Global’s premier research database, InfoSci-Journals.

Linguistic variables with equivalent triangular fuzzy numbers were used to elucidate judgment of elements in pairwise comparison matrices within the context of the analytic network process. Analytic network process effectively handles the complexity of the decision-making problem resulting from the subjectivity and interrelationships inherent among decision components. Domain experts in manufacturing strategy and sustainability were asked to elicit judgment in pairwise comparisons. Results show that the content of the infrastructural decisions of manufacturing strategy remains constant regardless of the presences of firm size component. However, the priority of each decision to the goal which can be translated as the priority of implementation of each policy varies with the presence of firm size.</p><p>This article is available on IGI Global’s premier research database, InfoSci-Journals.

The aim of research is to study the strength related characteristics of solid state joints formed with Al/SiCp composites using continuous drive friction welding process. The dominant welding parameters included in study are frictional pressure, upset pressure, speed of rotation and burn off length. The mechanical properties such as proof stress, tensile strength and Vickers hardness are observed for various joints, formed using a L27 orthogonal array design. The optimal welding condition is sorted out using Taguchi principles integrated with technique for order of preference by similarity to ideal solution (TPIT) method, taking into account the factor interactions as well. The approach is validated through the confirmation test. ANOVA is performed to supplement the TPIT method and upset pressure is identified as the prime parameter affecting the responses. The microscopic images of fractured surfaces are also examined.</p><p>This article is available on IGI Global’s premier research database, InfoSci-Journals.

Fractal surface is generated from the modified Weierstrass-Mandelbrot function and is imported to ANSYS to construct the finite element model of the same. A parameter called ‘nonlinearity exponent', is obtained from the force-displacement relationship of the rough surface and is used to find out the dynamic properties of the contacting interface using single spring-mass-damper model. The effect of variation in surface roughness and material properties on the system response is analyzed. The system exhibits superharmonic responses for different values of the nonlinearity exponent. The phase plot and time-displacement plots for the system are also furnished.</p><p>This article is available on IGI Global’s premier research database, InfoSci-Journals.

The model relationship connects attenuation with some parameters of cable design and testing: copper wire, aluminum, and insulation thicknesses, cable impedance, test frequency, and lay length. Defined expression was used for Monte-Carlo simulation of the cable attenuation prediction. With developed MATLAB program, a special graphical user interface was created. After assigning the desired parameters, this interface generates a plot with distribution of the attenuation values and required attenuation limit, and outputs defined mean attenuation, its 98% error, and numbers of values that get in and out of the limiting value. Data of calculations were verified by experiments and reveal good concurrence with the actual data. The realized fitting and simulation procedure, together with developed programs and created interface can be used as compact tool for designing cables with optimal parameters.</p><p>This article is available on IGI Global’s premier research database, InfoSci-Journals.

So it is important to understand dynamics of cracked structures. Crack depth and location are the main parameters influencing the vibration characteristics of the rotating shaft. In the present study, a technique based on the measurement of change of natural frequencies has been employed to detect the multiple cracks in rotating shaft. The model of shaft was generated using Finite Element Method. In Finite Element Analysis, the natural frequency of the shaft was calculated by modal analysis using the software ANSYS. The Numerical data were obtained from FEA, then used to train through Adaptive Neuro-Fuzzy-Inference System. Then simulations were carried out to test the performance and accuracy of the trained networks.

The main function of cylinder Head Gasketed joint is to seal combustion gases, oil and coolant and avoid entering the air into combustion chamber. Preload is applied on cylinder head bolt to avoid the leakages. Excessive preload on cylinder head bolt will cause extra stresses and cylinder bore deformation also increased which reduces the engine performance. Hence, it is very essential to determine adequate and accurate preload on cylinder head bolts. There are different types of bolt tightening methods followed by engine manufacturers as compared to other methods loss of preload and preload variation is less in angle torque method. In this work, Angle torque method for cylinder head bolted joint classical mathematical model is developed to estimate the snug torque and angle torque. Model is validated with FE analysis and experimental work. High performance 3-cylinder diesel engine's cylinder head, cylinder head bolts and crankcase are taken for methodology development, FE and experimental work.</p><p>This article is available on IGI Global’s premier research database, InfoSci-Journals.

The composites were produced by the addition of oxide particles in different weight percentage. The effect of oxide powder addition on microstructure and mechanical properties of produced composites were investigated. The effect of heat treatment on microstructure and mechanical properties were investigated by optical microscope, Microhardness tester and tension test. A significant improvement in hardness and tensile strength was revealed in the produced composite as compared to the base alloy. With the addition of oxide particles, the shape and size of eutectic Si changed which in turn affects the properties. It was observed that 2h solutionizing followed by the artificial aging was sufficient to make the structure homogenize and to produce the hardening precipitates.

Hardness also depends on the microstructure of metallic alloys. The present study explores the correlation between hardness and fracture toughness for different microstructures in order to calibrate loss in toughness from hardness.

The cooling system has a great importance in the engines. It coolants overheat of the engine, and prevents it from breakdown, that's why a highly reliable cooling system is the necessity of every engine but there are many failure issues with a cooling system which are time dependent. This paper investigates the performance of a water cooling system with the consideration of their significant components by taking the attention of three types of time dependent failure issues while the water cooling system is maintained by the sufficient repair facility. It is obvious that in the lack of maintenance, failure issues in water cooling system lead with the increment of time. Maintenance and operating costs of water cooling system affect the economy of overall engine very much, so, it is necessary to be aware about overheating of engines during peak ambient conditions when it is operated with full capacity.

The welding deformation was experimentally evaluated using a single-mode fiber laser with a high-speed scanning system. Application of developed thermal model demonstrated that the laser parameters, such as laser power, scanning velocity and spot diameter have a significant effect on temperature field and the weld pool. In the case of welding deformation, numerical simulation was carried out by an uncoupled thermo-mechanical model. The welding stress and deformation are generated by plastic deformation during the heating and cooling periods. It was confirmed that the residual stress is higher than yield strength and has strongest effect upon the welding deformation.

There is a demand to study nano-metric cutting mechanisms and phenomena appearing in this level. However, experiments are difficult to be realized, so computational methods are employed. Nano-scale cutting involves workpiece deformation in only a few atomic layers from the workpiece surface; at this scale the continuum theory cannot be used, so methods like finite elements are not sufficient. Molecular Dynamics is a method increasingly used for the simulation of nano-cutting. However, the computational cost required is quite high. In an effort to reduce the time of the analysis, high or extremely high cutting speeds are used in the models. In this paper an analysis is presented where cutting speed is studied and its influence on the chip morphology and workpiece surface is investigated, for nano-cutting modelling of Cu with diamond tools. The results indicate that cutting speed influences the outcome of the analysis and more attention should be paid to the selection of this parameter.</p><p>This article is available on IGI Global’s premier research database, InfoSci-Journals.

An assumption has been made that the air-gear oil mist within transmission is under steady state condition, in isothermal equilibrium with the transmission gear oil bath of lubricant. The lubrication in multi speed transmission is subjected to thermo-elastohydrodynamic lubrication. The study here analyzed transmission in second gear pair. In full torque loading condition the high temperature generated due to meshing action of gears and frictional conditions between the transmission gear train changes the thermo-physical property of gear oil. The overall vehicle transmission gearbox performance is governed by the gear oil properties and it also effects the fuel consumption. This research study was performed at two higher different temperature range of gear oil.The analysis result shows that the gearbox oil thermal properties directly effect the performance and life span of automobile transmission gearbox.</p><p>This article is available on IGI Global’s premier research database, InfoSci-Journals.

In the present work, vibratory setup has been used for inducing mechanical vibrations into the weld pool during welding. The designed vibratory setup produces the required frequency with the amplitude and acceleration in terms of voltages. An increase in the flexural strength of the weld pieces in to the heat affected zone (HAZ) has been observed. The increase in mechanical properties is attributed to, as the weld pool solidifies, grains are not only limited in size but also dendrites are broken before they grow large in size. Refined microstructure has been observed. The above mechanism is responsible for the improvement in flexural strength of weld pieces welded with vibratory setup compared to without vibration during welding.</p><p>This article is available on IGI Global’s premier research database, InfoSci-Journals.

The laser fabricated joints were characterized by optical microscopy and scanning electron microscopy to reveal the metallurgical features. A uniaxial tensile test was carried out to measure the mechanical strength of the porosity free welds, and porosity bearing welds. The results showed that the welds bearing gaseous porosity performed nearly 24% lower mechanically than the porosity free welds. Fractography exposed the presence of fine spherical holes in porosity bearing welds, which acted as crack nucleation sites, and their further growth lead to a sudden failure at higher strain rates. Microstructural observations revealed that the laser processing has transformed the superior age-hardened microstructure of the base metal into a new as-cast microstructure. The freshly evolved microstructure was held responsible for the low mechanical properties of the joints with respect to the base metal.</p><p>This article is available on IGI Global’s premier research database, InfoSci-Journals.

However, light aircraft rely only on the cabin structure to withstand the compression and energy generated during a crash. This study performed a topology optimization analysis on the model structure by using Abaqus/optimization and used strain energy as the objective function and cabin volume as a constraint to develop the optimal model. Subsequently, this work performed dynamic crash simulations based on the optimal and original models by using Abaqus/explicit. Compared with the original model, the optimal model yielded a 12% increase in the safety zone of the diagonal beams, a 13% increase in the X-direction safety zone, and a 10% increase in the overall safety zone.

For that reason, the application of a global method, which may escape from the locally minimum points, remain essential. In this paper, a new hybrid simulated annealing algorithm for large scale global optimization problems with constraints is proposed. The authors have developed a stochastic algorithm called SAPSPSA that uses Simulated Annealing algorithm (SA). In addition, the Simultaneous Perturbation Stochastic Approximation method (SPSA) is used to refine the solution. Commonly, structural analysis problems are constrained. For the reason that SPSA method involves penalizing constraints a penalty method is used to design a new method, called Penalty SPSA (PSPSA) method. The combination of both methods (Simulated Annealing algorithm and Penalty Simultaneous Perturbation Stochastic Approximation algorithm) provides a powerful hybrid stochastic optimization method (SAPSPSA), the proposed method is applicable for any problem where the topology of the structure is not fixed. It is simple and capable of handling problems subject to any number of constraints which may not be necessarily linear. Numerical results demonstrate the applicability, accuracy and efficiency of the suggested method for structural optimization. It is found that the best results are obtained by SAPSPSA compared to the results provided by the commercial software ANSYS.</p><p>This article is available on IGI Global’s premier research database, InfoSci-Journals.

The process of boronizing can produce extremely hard and wear resistant surfaces for such components. The study depicts the application of Taguchi based desirability analysis for parameter design in the process of boronizing martensitic stainless steel. The surface hardness, diffusion depth and wear loss were observed on samples subjected to slurry paste boronizing (SPB). During experimentation, the parameters varied include the boronizing temperature, boronizing time and paste thickness. The optimal setting of the boronizing parameters identified by Taguchi based desirability analysis (TDA) was observed to improve the quality characteristics studied in the process significantly. The duration of boronizing process was found to play a major role in controlling the diffusion depth and the formation of a mono phasic (FeB) layer on the surface was found to be the reason for improved hardness and wear resistance.</p><p>This article is available on IGI Global’s premier research database, InfoSci-Journals.

ECMM improves dimensional accuracy and simplifies tool design for machining hard, high strength, heat resistant, and conductive materials into complex shapes. Extremely small interelectrode gaps of the order of few microns are required in ECMM for better dimensional accuracy. However, excessively small interelectrode gaps may lead to complications, such as short-circuiting, which disrupt the stability of ECMM process. This necessitates the need for better understanding of the interelectrode gap dynamics. This paper presents a mathematical model for the analysis of interelectrode gap under non-steady state conditions in micromilling of steel using the ECMM process. Experimental verification of the mathematical model was conducted using an in-house built micro electrochemical machining system. The model is capable of predicting the machining results to within 1- 5 µm error (10- 50%).</p><p>This article is available on IGI Global’s premier research database, InfoSci-Journals.

The thermal energy has been frequently utilized for improving machinability characteristics of Inconel 718. The review of available literature indicates that plasma, laser, and electric discharge have been the major sources used for the enhancement of tool life, material removal rate, surface integrity, and reduction of cutting forces during machining of Inconel 718. However, a very few efforts have been made as regards to the use of wire electrical discharge machining and other energies like mechanical, electrochemical, and chemical for machining of this material. Moreover, the reported work on machining of Inconel 718 is largely focused on drilling operations.

Electroless nickel coatings are mainly used for wear and corrosion resistant properties. However, additional characteristics like smoothness of deposit, low friction, descent plating rate, electrical and magnetic properties also make them suitable for a host of applications. The properties of electroless nickel coatings depend mainly on the electroless solution ingredients as well as deposition conditions. Important deposition parameters include bath temperature, concentration of nickel source, concentration of reducing agent, pH of the solution, concentration of surfactants, and so on. Moreover, heat treatment is found to modify the microstructure of the coating and influence certain properties viz. hardness, wear resistance, corrosion resistance, etc. A large number of works have been published by the researchers on the evaluation of electroless nickel coating performance on the basis of hardness, roughness, corrosion resistance, friction and wear resistance for various types of coatings and substrates. Several approaches are proposed in the literatures to solve the problems related with optimization of these parameters. It is felt that a review of the various approaches developed would help to compare their main features and their relative advantages or limitations which will enable to choose the most suitable approach for a particular application and also throw light on aspects that needs further attention. In this regard, the present paper presents a review on the developments done on the optimization of electroless nickel coatings to increase its efficiency.</p><p>This article is available on IGI Global’s premier research database, InfoSci-Journals.

The internal harmonic excitation produces a dynamic mesh force, which is transmitted to the housing through the shafts and bearings and causes transmission failure. The main objective of this research work is to study the relation between the transmission vibration and the positional fixed constraints of vehicle frame by comparing the free vibration results of zero displacement constraint condition to positional constraint of the different number of connecting bolts. The vehicle gearbox housing is mounted on vehicle frame using connecting bolts fixture. The present design of heavy vehicle truck transmission housing is mounted on vehicle frame using 37 connecting bolts on five different positions. The study has been completed in two parts, in first parts all 37 connecting bolts were fixed on vehicle frame and in second part of study the front and bottom positional bolts were loosened to study the relation between vibration and constraint connecting bolts. Reciprocity Principle was used to apply the loads on housing. The first 20 vibration mode shape and natural frequencies were calculated using ANSYS 14.5. The study has theoretical and practical importance for the structure optimization of gearbox housing. ANSYS 14.5 is used as FEA based analysis tool. The natural frequency for zero displacement condition varies from 1669 Hz to 3576 Hz and for loose transmission housing frequency varies from 750 Hz to 3802 Hz. The analysis results is verify with experimental results available in literature.</p><p>This article is available on IGI Global’s premier research database, InfoSci-Journals.

A combined technique using orthogonal array and analysis of variance (ANOVA) was employed to investigate the contribution of spindle speed, feed rate, depth of cut and air pressure on responses. Utilization of IR camera is been effective to calculate the temperature at the interface of workpiece and the tool. It is observed that with spray impingement cooling, cutting performance improves compared to dry cutting. The predicted multi response optimization setting (N3-f1-d1-P2) ensures minimization of surface roughness, cutting temperature and maximization of material removal rate.

The results of the experiment showed that the hard turning can be applied for the finish machining of chrome plated surfaces. The influence of hard turning was observed when it was tested for residual stress distribution. The results disclosed that the chrome plating technhique has induced the compressive residual stress of -355.9MPa in the workpieces. These compressive residual stresses increased to a value of -723.3MPa after hard turning the chrome plated surfaces. But with worn out insert a tensile residual stress of 228.1MPa was observed in the workpiece. The results also revealed the variation of flank wear on the tool with different cutting inserts. The conclusions was drawn on the hard turning of hard chrome plated by adopting proper cutting conditions to replace the grinding operation by hard turning operation.</p><p>This article is available on IGI Global’s premier research database, InfoSci-Journals.

However, they still suffer from several nonlinearities like deadband in electrohydraulic valves, hysteresis, stick-slip friction in valves and cylinders. In addition, all hydraulic system parameters have uncertainties in their values due to the change of temperature while working. This paper addresses these problems by designing a suitable intelligent control system that has the ability to deal with the system nonlinearities and parameters uncertainties using a fast and online learning algorithm. A novel hybrid control system based on Cerebellar Model Articulation Controller (CMAC) neural network is presented. The proposed controller is composed of two parallel controllers. The first is a conventional Proportional-Velocity (PV) servo type controller which is used to decrease the large initial error of the closed-loop system. The second is a CMAC neural network which is used as an intelligent controller to overcome nonlinear characteristics of the electrohydraulic system. A fourth order model for the electrohydraulic system is introduced. PV controller parameters are tuned to get optimal values. Simulation and experimental results show a good tracking performance obtained using the proposed controller. The controller shows its robustness in two working environments. The first is by adding different inertia loads and the second is working with noisy level input signals.</p><p>This article is available on IGI Global’s premier research database, InfoSci-Journals.

Thus, mathematical models for quick prediction of these aspects are needed because experimental determinations of process performances are always tedious and time consuming. Not only prediction but determination of optimum parameter for optimization of process performance is also required. This paper attempts to apply a hybrid mathematical approach comprising of Back Propagation Neural Network (BPNN) for prediction and Grey Relational Analysis (GRA) coupled with Principal Component Analysis (PCA) for optimization with multiple responses of HS-EDMM of Invar-36. Experiments were conducted to generate dataset for training and testing of the network where input parameters consist of gap voltage, capacitance of capacitor and the resulting performance parameters MRR, TWR and Ta. The results indicate that the hybrid approach is capable to predict process output and optimize process performance with reasonable accuracy under varied operating conditions of HS-EDMM. The proposed approach would be extendable to other configurations of EDMM processes for different material.</p><p>This article is available on IGI Global’s premier research database, InfoSci-Journals.

Therefore, while employing these different dielectrics, dissimilar process responses are accounted when machining in EDM at micron level. The present paper investigates micro-EDM characteristics such as material removal rate (MRR), tool wear rate (TWR), overcut (OC), taperness and machining time (MT) during micro-machining of through holes on Ti-6Al-4V superalloy employing de-ionized water based dielectric other than conventional hydro-carbon oil i.e. kerosene. The paper also includes the comparative study of the micro-EDM machining characteristics employing boron carbide (B4C) powder as additive in de-ionized water dielectric at different discharge energies. The results show that MRR and taper of micro-hole are better and TWR is less employing B4C additive in the dielectric than pure one, i.e. the productivity is improved and same micro-tool can be used for machining an array of micro-holes. Surface topography and recast layer formed during micro-hole machining by micro-EDM has also been investigated based on optical and SEM micrographs. Energy dispersive spectroscopy (EDS) analysis of machined surface as well as tool electrode surface has been done and the results show that there is significant amount of infusion of tungsten element onto the machined surface. A significant amount of carbon element is found onto the tool electrode surface.</p><p>This article is available on IGI Global’s premier research database, InfoSci-Journals.

In the present work an attempt has been made in order to investigate the Thrust force generated during drilling of the TiO2 and ZnS filled Glass Fabric Reinforced Polymer Matrix Composites (GFRP). The volume fractions in the matrix were chosen as 1, 2 and3%. A plan of experiments, based on the techniques of Taguchi, was performed to acquire data in a controlled way. An L27 orthogonal array and analysis of variance (ANOVA) were employed to investigate the influence of process parameters on the drilling of these composites. Drilling has been conducted on a radial drilling machine. Speed of drilling (S), volume fractions (VF) and drill tool diameter (D) were considered as the varying parameters with three levels. Thrust force has been considered as the output parameter and is been measured in each combination of parameters chosen. Results reveal that, the addition of filler will increase the thrust force developed during drilling. As per ANOVA values, drill tool diameter contributes more towards generation of thrust, followed by speed of drilling. Main Effect plots shows that, contribution of speed towards thrust generation is only upto a certain level of increase in speed.</p><p>This article is available on IGI Global’s premier research database, InfoSci-Journals.

At present, throughout the globe, this task performed by overhead transmission lines. The dual task of mechanically supporting and electrically isolating the live phase conductors from the support tower is performed by insulators. The electrical potential, field and temperature distribution along the insulators governs the possible effects, which is quite detrimental to the system. However, a reliable data on electrical potential, field and temperature distribution in commonly employed insulators are rather scarce or access individually for thermal or electrical load only. Considering this, the present work has made an attempt to study accurately, thermal and electrical characteristics of 11 kV single cap and pin type ceramic disc distribution insulator assembly used for high voltage transmission. The coupled field thermo electrical finite element by using commercially available FEM software Ansys-11 is employed for the required field computations. This new set of ANSYS coupled-field elements enables users to accurately and efficiently analyze thermoelectric devices. This paper review the finite element formulation, which in addition to Joule heating, includes Seebeck, Peltier, Thomson effects and electrical load, i. e. by considering thermal and electric loads acting simultaneously. The Electrical voltage, electrical field and temperature distribution is deduced and compared with various other/individual analyses.</p><p>This article is available on IGI Global’s premier research database, InfoSci-Journals.

One of the critical factors in achieving nanoscale precision during the VANILA process is to maintain an optimal machining gap between the tool and the workpiece surface. Piezoelectric crystal based positioning systems is a proven method for achieving ultraprecision control, however the application of such a system for controlling the nanoscale machining gap during a machining process is not explored. In this paper, the possibility of using a piezoelectric crystal based nano positioning setup to achieve the desired gap during the VANILA process is explored. This research thus finds a new application for the nanopositioning systems in order enhance the capability of existing VANILA process. Analytical models based on piezoelectric theory are done to predict the vibrational behavior of the piezoelectric crystal in the nano-positioning setup under different machining conditions. Further experiments are conducted to validate the model and study the mass-loading effect on the piezoelectric crystal. The model developed is agreeing within 20% with the experimentally determined values and thus the model forms the basis for using the nano-positioning system for maintaining optimal gap between the tool tip and the workpiece surface.</p><p>This article is available on IGI Global’s premier research database, InfoSci-Journals.

But the adverse health effects caused by the use of flood coolants are drawing manufacturers' attention to develop methods for controlling occupational exposure to cutting fluids. Microlubrication serves as an alternative to flood cooling by reducing the volume of cutting fluid used in the machining process. In this study the effects of microlubrication during end milling of AISI 1018 steel was investigated using vegetable based cutting fluid aerosol. A solid carbide cutting tool was used with varying cutting speeds and feed rates having a constant depth of cut. A full factorial experiment was conducted and regression models were generated along with parameter optimization for the aerosol mass concentration and the aerosol particle size. The study shows that with a proper selection of the cutting parameters it is possible to reduce the aerosol mass concentration in end milling under microlubrication. But more scientific assessments are needed to lower the mass concentration of the aerosol particles, below the recommended value of 5 mg/m3 by Occupational Safety and Health Administration (OSHA). Limited studies have been reported to investigate the effectiveness and quality of mist produced under microlubrication. No study has been reported to date on end milling 1018 steel under microlubrication.</p><p>This article is available on IGI Global’s premier research database, InfoSci-Journals.

Two different geometry configurations of the T-joints have been used, namely Type-1 and Type-2. An elastic analysis has been considered. The Static loading conditions used are: axial load, compressive load, In-plane bending (IPB) and Out-plane bending (OPB). The natural frequencies analysis (dynamic loading condition) has also been carried out. The geometry configurations of the T-joints have been used, vertical tubes are called brace and horizontal tubes are called chords. The joint consists of brace joined perpendicular to the circular chord. In this case the ends of the chord are held fixed. The material used is mild steel. Using ANSYS, finite element modeling and analysis of T-joint has been done under the aforementioned loading cases. It is one of the most powerful methods in use but in many cases it is an expensive analysis especially due to elastic–plastic and creep problems. Usually, three dimensional solid elements or shell elements or the combination of two types of elements are used for generating the tubular joints mesh. In tubular joints, usually the fluid induced vibrations cause the joint to fail under resonance. Therefore the natural frequencies analysis is also an important issue here. Generally the empirical results are required as guide or comparison tool for finite element investigation. It is an effective way to obtain confidence in the results derived. Shell elements have been used to model the assembled geometry. Finite element ANSYS results have been validated with the LUSAS FEA and experimental results, that is within the experimentation error limit of ten percentage.</p><p>This article is available on IGI Global’s premier research database, InfoSci-Journals.

In particular, intensive efforts have been directed toward synthesizing, characterizing and understanding polymer/CNT composites. In this paper, as an effort to explore the effective use of carbon nanotubes as a reinforcing material for advanced nanocomposites with polymer matrix, a single walled carbon nanotube (SWCNT) is used to reinforce Nylon 6 matrix. Molecular dynamics (MD) simulations are used to study two periodic systems - a long CNT-reinforced Nylon 6 composite and amorphous Nylon 6 matrix itself. The axial and transverse elastic moduli of the amorphous Nylon 6 matrix and nanocomposites are evaluated using constant-strain energy minimization method. The results from molecular dynamics simulations are compared with corresponding rule-of-mixture predictions. The simulation results show that CNTs significantly improve the stiffness of Nylon 6/CNT composite, especially in the longitudinal direction of the nanotube. The conventional rule-of-mixture predicts a much larger value than MD simulation for the nanocomposite.</p><p>This article is available on IGI Global’s premier research database, InfoSci-Journals.

On the other hand, increased environmental regulation has urged firms to compulsorily have their routine operations environmental friendly. Last few years, researchers have investigated these two streams as distinct but have mentioned them to be related in the long run. The current study attempts to bridge this gap of allied literature by conceptually arguing that it to arrive at sustainability in supply chain operations, firms must co-integrate their supply chain risk management and green practices in supply chain. While risk management broadly aims to reduce the exposure to a risky situation coupled with minimizing the negative impact of disruption of firm performance; green practices aims to make operational, tactical and strategic operations of the firm environment friendly. Based on sufficient theoretical tenets from related literature, the study attempts to develop a theoretical model linking supply chain risk management, green supply chain practices and sustainable supply chain. In doing so, the study provides an indicative list of various risk classifications and proposed risk mitigating strategies till date. Finally, the study indicates managerial implications and suggests further research opportunities.</p><p>This article is available on IGI Global’s premier research database, InfoSci-Journals.

Hence accurate prediction of weld bead parameters is highly essential to achieve good quality joint. This paper presents development of neural network models for predicting bead parameters such as depth of penetration, bead width and depth to width ratio for AISI 202 grade stainless steel GTAW plates. The use of this series in certain applications ended in failure of the product as there is no adequate level of user knowledge. Hence it becomes imperative to go for detailed investigations on this grade before recommending it for any application. The process parameters chosen for the study are welding current, welding speed, gas flow rate and welding gun angle. The chosen output parameters were depth of penetration, bead width and depth to width ratio. The experiments were conducted based on design of experiments using fractional factorial with 125 runs. Using the experimental data feed forward back propagation neural net work models were developed and trained using Levenberg Marquardt algorithm. The training, learning, performance and transfer functions used are trainlm, learningdm, MSE and tansig respectively. Four networks were developed with four neurons for the input layer, 3 neurons for the output layer and different nodes for the hidden layer. They are 4 – 2 – 3, 4 – 4 – 3, 4 – 8 – 3 and 4 – 9 – 3. It was found that ANN model based on network 4 – 9 – 3 predicted the bead dimensions more accurately than the other networks. The prediction of weld bead geometry parameters helps in identifying the recommended combination of process parameters to achieve good quality joint.</p><p>This article is available on IGI Global’s premier research database, InfoSci-Journals.

The improvement of the proposed IRBF network is carried out in two stages. Conventional RBF network is used in the first stage for preliminary damage prediction and in the second stage reduced search space moving technique is used to minimize the prediction error. The network is trained with fractional frequency change ratios (FFCs) and damage signature indices (DSIs) as effective input patterns and the corresponding damage severity values as output patterns. The patterns are searched at different damage levels by Latin hypercube sampling (LHS) technique. The performance of the novel IRBF method is compared with the conventional RBF and Genetic algorithm (GA) methods and it is found to be a good multiple member damage identification strategy in terms of accuracy and precision with less computational effort.</p><p>This article is available on IGI Global’s premier research database, InfoSci-Journals.

The proposed implementations are suitable in applications like various motors, generators, aircrafts, battle field and elevators, etc where noise reduction is very important. In the experiments, the authors used several variants of the familiar Filtered X Least Mean Square (FXLMS) algorithm. In FXLMS the vector of past inputs is first filtered by the secondary path transfer function, hence it is named as filtered X LMS. These modified results normalized FXLMS (NFXLMS) and normalized clipped FXLMS (NCFXLMS) algorithms, leads to fast convergence, better noise rejection capability. The NCFXLMS algorithm requires only half of the multiplications requires than NFXLMS. This type of low complexity strategy is not used in active noise control application in mechatronic systems. Simulation results prove that the proposed active noise cancellers provide better performance in terms of signal to noise ratio than the conventional FXLMS.</p><p>This article is available on IGI Global’s premier research database, InfoSci-Journals.

First, ANN with backpropagation algorithm was used to model the LBC of nickel based superalloy sheets. The input process parameters taken were oxygen pressure, pulse width, pulse frequency and cutting speed. The performance characteristics of interest in nickel based superalloy thin sheet cutting are average kerf taper and surface roughness. The ANN model was trained and tested using the experimental data obtained through experimentation on pulsed Nd-YAG laser beam machining system. The 4-10-11-2 backpropagation architecture was found more accurate and generalized for given problem with good prediction capability. The results show that the developed modelling and optimization tool is effective for process parameter optimization in LBC process. The optimization of the process suggests that for achieving high cut quality characteristics the pulse width, pulse frequency and cutting speed are set to lower limit within the available range and gas pressure is set to a level which is sufficient to remove the molten metal from the kerf.</p><p>This article is available on IGI Global’s premier research database, InfoSci-Journals.

Paris law is used to develop the fatigue shape of initially semi-elliptical surface crack. Because of needs for the higher mesh density and accuracy near the crack, the sub-modeling technique is used in the analysis. The distribution of SIF’s along the crack front at each step of growth is studied and the effect of crack orientation on the rate of crack-growth is investigated. The calculated SIF’s are reasonable and could be used to predict the probable crack growth rates in fracture mechanics analysis and can help engineers to consider in their designing and to prevent any unwanted failure of such components.</p><p>This article is available on IGI Global’s premier research database, InfoSci-Journals.

Use of CGI, that have higher strength and stiffness as compared to FGI, allows engine to perform at higher peak pressure with higher fuel efficiency and lower emission rate. However, not only for its potential, CGI is of an area of interest in metal cutting research because of its poor machinability as compared to that of FGI. The higher strength of CGI causes a faster tool wear rate in continuous machining operation even in low cutting speed as compared to that for FGI. This study investigated the influence of cutting edge geometry at different cutting parameters on the machinability of CGI in terms of tool life, cutting force and surface roughness and integrity in internal turning operation under wet condition. It has been seen that the cutting edge radius has significant effect on tool life and cutting forces. The results can be used to select optimum cutting tool geometry for continuous machining of CGI.</p><p>This article is available on IGI Global’s premier research database, InfoSci-Journals.

Cryogenic treatment of tooling steels is a proven technology to increase wear resistance and extend intervals between component replacements. The main idea of this paper is to apply Taguchi method to optimize cutting parameters in turning operation using cryogenic treated (CT) and untreated (UT) high speed steel (HSS) tools, so that the scope of cryogenic treatment on HSS tool material may be presented for the benefit of medium and small scale industry using HSS tools for cutting operation. Taguchi L25 orthogonal array is employed to study the performance characteristics in turning operations of AISI 1020 steel bars using CT and UT HSS tools. The microstructure has been found more refined and uniformly distributed after cryogenic treatment of HSS tool. It has been observed that optimum machining parameters in both the cases (CT HSS and UT HSS tools) are higher cutting speed (49.9 to 75.7 m/min.), lower feed rate (0.15 mm/rev.), medium depth of cut (0.40 mm). Analysis of variance (ANOVA) indicates that the cutting speed is most significant parameter followed by feed rate in case of CT HSS tool and depth of cut in case of UT HSS tool.</p><p>This article is available on IGI Global’s premier research database, InfoSci-Journals.

In this paper, a single walled carbon nanotube (SWCNT) is used to reinforce polystyrene matrix. Molecular dynamics (MD) simulations are used to study two periodic systems - a long CNT-reinforced polystyrene composite and amorphous polystyrene matrix itself. The axial and transverse elastic moduli of the amorphous polystyrene matrix and nanocomposites are evaluated using constant-strain energy minimization method. The results from MD simulations are compared with corresponding rule-of-mixture predictions. The simulation results show that CNTs significantly improve the stiffness of polystyrene/CNT composite, especially in the longitudinal direction of the nanotube. Polystyrene posses a strong attractive interaction with the surface of the SWCNT and therefore play an important role in providing effective adhesion. The conventional rule-of-mixture predicts a smaller value than MD simulation where there are strong interfacial interactions. Here the authors report a study on the interfacial characteristics of a CNT-PS composite system through MD simulations and continuum mechanics.</p><p>This article is available on IGI Global’s premier research database, InfoSci-Journals.

The coupled field finite element computer simulation is carried out by using a commercially available software package, which allows quantifying the effects of insulator assembly on where structural, thermal and electrical load distribution considered simultaneously. The simulation result shows stress concentration due to application of structural, thermal, and electrical load. The stress was maximum on pin and moderate on sealing material and disc. Similarly in electrical analysis, nodal electrical potential and electrical field distribution observed decreasing from bottom pin of insulator assembly to top cup end of insulator model. Remarkable stresses, temperature, electrical potential and electrical field rise was not observed at porcelain but mainly observed in critical areas like triple junction (pin-porcelain, porcelain-cup junction of insulator assembly), despite high tension, high temperature of conductor and high voltage-current. With continuous use of an insulator and varying environmental condition, this high tension, temperature and high voltage may cause small crack in sealing material and the insulator disc material. This may reduce performance or cause failure of an insulator without any prior notice.</p><p>This article is available on IGI Global’s premier research database, InfoSci-Journals.

A few design modifications or use of different size and grades of materials solves this problem greatly. This paper focuses upon the metal finishing process of Laser Welded Blanks (LWB) with simulation and reliability as well as new process development. These blanks are of same gauge-same gauge or different gauge-different gauge materials. The main aim of this process was to remove the visible portion of the weld on the blank, so that it can be used as a body-outer. A new process was developed using expert knowledge and automated machinery tools. A simulation model was developed to compare with the actual developed method and to detect the bottlenecks and optimize the process. Reliability was a major concern during laser-welded blank operations. The paper addresses prediction of the amount of material removed based on the failed parts and visibility of the weld. This approach could provide competitiveness in the weight of the car which is directly related to fuel efficient and long term survival.</p><p>This article is available on IGI Global’s premier research database, InfoSci-Journals.

This work is focused on the influence of the work piece slenderness ratio and cutting parameters on the quality of the machined part, assessed in terms of surface roughness and both geometric (run-out) and dimensional (diameter) deviations. Turning tests with coated tungsten carbide tools were performed using AISI 1045 medium carbon steel as work material. Differently from the published literature, a statistical analysis based on the multivariate one-way analysis of variance (MANOVA) was applied to the data obtained using a Box-Behnken experimental design. In order to identify the combination of parameters (slenderness ratio, cutting speed, feed rate and depth of cut) levels which simultaneously optimize the responses of interest (surface roughness, run-out and diameter deviation), a multivariate optimization method based on principal component analysis (PCA) and generalized reduced gradient (GRG) was employed.</p><p>This article is available on IGI Global’s premier research database, InfoSci-Journals.

Several composite laminates were obtained by changing the number of plies, the rubber powder size distribution, and the stacking sequence. Quasi-static mechanical tests (tensile and flexure) and time dependent tests (dynamic mechanical analysis and cyclic flexure) were carried out to evaluate strength and damping properties. As expected, 10 wt% rubber-filled laminates showed lower strengths than rubber-free laminates but the effect of the rubber on the composite damping properties was evident. At low rates, the rubber particles can also double the dissipated energy under cyclic loading, even if this effect disappears by increasing the test rate.</p><p>This article is available on IGI Global’s premier research database, InfoSci-Journals.

Several management strategies have been used for the control of pathogenenic fungi. Each of these methods has one or other limitations. Due to hazardous effects caused by excessive use of pesticides, scientists in the agricultural field are searching for alternative measures against pesticides. As an alternative to chemically manufactured pesticides, use of nanoparticles as antimicrobial agents has become more common as technological advances. Until now, limited research provided some evidence of the application of nanoparticles for the control of plant diseases caused by fungi. In the present study antimycotic activity of nanoparticles of magnesium, Iron and zinc have been investigated under in-vitro conditions and was observed from the study that all the nanoparticles at different concentrations brought about significant inhibition in the germination of spores of Penicillium notatum, Aspergillus niger, and Nigrospora oryzae Berk. However, the highest inhibition in the germination of all the test fungi was observed at higher concentrations followed by lower concentrations of nanoparticles. The nano MgO at highest concentration was found most effective in reducing the spore germination followed by nano-FeO and nano-ZnO at the same concentration respectively.</p><p>This article is available on IGI Global’s premier research database, InfoSci-Journals.

In the experimentation, the width of the sample to bend was changed as well as laser power and scan rate. The effect of other process parameters was also investigated; the surface aspect and the sample orientation with regard to the rolling direction. Mechanical tests and surface analyses were performed before and after laser testing so as to deepen the laser-material interaction. A thermal numerical model was also implemented to study the effect of the laser power on the laser beam absorption during processing. As a result, a good bendability of the 5005 alloy sheets was observed though many parameters need to be considered for the process control. A simple process map for line bending can be extracted from experimental data only if some of those parameters are fixed; above all the sample orientation. These results are found to be significant in better understanding the bending behavior of thick aluminum sheets with high density laser power when a complex interaction between process and material parameters is present.</p><p>This article is available on IGI Global’s premier research database, InfoSci-Journals.

Heat transfer phenomena in high speed deep surface grinding (HSDSG) is entirely different than conventional shallow cut grinding. Due to high wheel speed and large depth of cut, the temperature rise in the grinding zone becomes very high during high speed deep surface grinding. Therefore, investigation of the temperature distribution becomes important in such situations. In this paper, a two dimensional thermal based finite element model has been developed to investigate the transient temperature distribution within the contact zone as well as in the whole workpiece due to high speed deep surface grinding.

However, in some conditions hexapod suffers from stability problems. To solve the problem of stability, this paper proposes a new gait model of hexapod robot named offset model and also investigates the effects of morphological factor of hexapod robots on their locomotion. A comparison between the offset model and general model of hexapod robot is also included. The stability margin and error margin are used to indicate the stability of a hexapod robot, as it walks with different gaits in arbitrary directions. Two hexapod gaits are compared, which are the diametrical gait and the paired metachronal gait. The former is an artificial gait and the latter is a natural gait. The authors conclude that that the stability of a hexapod robot with the diametrical gait can be enhanced by increasing the offset parameter.</p><p>This article is available on IGI Global’s premier research database, InfoSci-Journals.

Three dimensional Navier Stokes equations along with a K-? turbulence model and infinitely fast kinetics are solved using commercial CFD software. Reasonable agreement has been obtained between the computed surface pressure with experimental values and the results of other numerical simulations. Insights into the flow features inside the combustor are obtained through analysis of various thermochemical parameters. The comparison of surface pressure with experimental results and other numerical results demonstrated that simple kinetics and turbulence – chemistry interaction model may be adequate to address the overall flow features in the combustor. A principal conclusion is that the boundary layer at the combustor entry has a pronounced effect on the flow development in the dual-mode scramjet combustor and causes significant upstream interaction.</p><p>This article is available on IGI Global’s premier research database, InfoSci-Journals.

The multi-response optimization of the machining parameters viz, chip-tool interface temperature, main cutting force and feed force on lathe turning of En-31 steel as alloy steel using RSM with grey relational analysis is reported. A grey relational grade obtained from the grey relational analysis is used to solve the turning operations with multiple performance characteristics. The models were developed using response surface methodology. Optimal cutting parameters can be determined by RSM method using the grey relational grade as the performance index. Chip-tool interface temperature, main cutting force, and feed force are important characteristics in turning operations. Using these characteristics, the cutting operations, including cutting velocity, feed rate, depth of cut, and effective tool nose radius, are optimized. A model is developed to correlate the multiple performance characteristic called grey relational grade and turning parameters and a new combination of RSM and grey relational analysis is proposed. The grey relational grades were significantly affected by cutting parameters and tool nose radius. Optimal parameter setting is determined for the multi-performance characteristic.</p><p>This article is available on IGI Global’s premier research database, InfoSci-Journals.

To analyze the influences of the various process parameters of ECSM setup, the specific numbers of experiments have been carried out on developed ECSM setup. The ECSM performance characteristics such as material removal rate, hole depth, and over-cut on hole radius during machining of e-glass-fibre-epoxy composite under varying process parametric conditions are reported in this paper. From the test results, it is found that at higher setting value of D.C. supply voltage, moderate setting value of electrolytic concentration and 180 mm gap between tool (cathode) and auxiliary electrode (anode) the material removal rate is higher. Utilizing the test results mathematical models for MRR and over-cut on hole radius have been developed to express the effect of ECSM process parameters.

Glycine and zinc nitrate, used as fuel and oxidant/cation sources respectively, were mixed together at room temperature to form a slurry or gel. A series of experiments were performed to synthesize nanoparticles for different fuel to oxidant ratios. The rate of heating and stirring greatly influenced the combustion process. The as-synthesized powder was heat treated at elevated temperatures for varying time to remove adsorbed impurities from the surface of the ZnO nanoparticles. Both the as-synthesized and heat treated powders were characterized using a variety of analytical techniques. The hexagonal wurtzite phase of the ZnO powder was revealed from x-ray diffraction measurements. A decrease in the x-ray diffraction density (Dx) and the bulk density (D) resulted in an increase in percentage porosity (%P) of as-synthesized and heat treated ZnO powders. The range of fuel to oxidant ratios used in the present work indicates that they had a strong influence on the grain size of ZnO powders. The average grain size estimated by using the Scherer formula indicated an approximate value of 6-21 nm for the as-synthesized and heat treated samples.</p><p>This article is available on IGI Global’s premier research database, InfoSci-Journals.

During the service, the suspension system is subjected to different environmental conditions, at the same time it has to sustain a variety of loads. The damage of the springs is mainly attributed by its load carrying capacity under fatigue loading. Fatigue strength is the most important property for the spring steel. The energy release rate is an important parameter used to predict the life of the springs. In this experimental analysis, the authors investigate the performance of spring steel under the action of fatigue loads. The specimen preparation and the experimentations have been carried out according to the American Society for Testing of Materials (ASTM) standards. From the experiments, the strain energy release rate of the spring steels has been determined. The effects of tempering and cryogenic treatments on the performance of the spring steel have also been determined. The results have revealed that the fatigue strength and the crack growth resistance have increased with quenching and cryogenic treatments.</p><p>This article is available on IGI Global’s premier research database, InfoSci-Journals.

During synthesis, the ZrB2 particle is formed by exothermic reaction within the aluminum melt. As a result, small, fine and oxide free reinforcements are formed. Excessive temperature released from in-situ chemical reaction will facilitate the homogeneous distribution of particles in entire shape of the composites. Making the engineering components from this composite material require machining operations. Therefore, addressing the machinability issues of the composite is very important. This paper proposes an approach to optimize the machining parameters in turning of Al 6061-6% ZrB2 in-situ Metal Matrix Composite (MMC) with multiple performance characteristics by using grey relational analysis. The effect of in-situ ZrB2 reinforcement particles on machinability behavior need to be studied. The machining parameters, namely cutting speed, feed rate and depth of cut are optimized with considerations of multiple performance characteristics including surface roughness, tool wear and cutting force. It is concluded that the feed rate has the strongest effect. The confirmation experiment indicates that there is a good agreement between the estimated value and experimental value of the Grey relational grade.</p><p>This article is available on IGI Global’s premier research database, InfoSci-Journals.

The design procedure of the ATVA is presented. The system consists of a cantilever beam mounted with shaker to generate the real-time vibration. The SMA spring with mass is attached at free end. The stiffness of SMA spring is varied dynamically in such a way to attenuate the vibration actively. Both simulation and experimentation are carried out. Simulation is carried out using Finite Element Analysis (FEA) package ANSYS software. The experiment was carried out by interfacing the experimental setup with computer along with LabVIEW software through data acquisition card (DAQ). In experimental setup, an accelerometer is used to measure the vibration which is fed to computer and in turn the SMA spring is actuated to change its stiffness which will control the vibration. The results illustrate that the developed ATVA using SMA is very effective in reducing structural response and having great potential to use as an active vibration control media.</p><p>This article is available on IGI Global’s premier research database, InfoSci-Journals.

More specifically, Third Wave Systems AdvantEdge commercial Finite Element Method code is employed in order to present turning models, under various machining conditions. As a novelty, the proposed models for High Speed Machining of steel are three-dimensional and are able to provide predictions on cutting forces, tool and workpiece temperatures, chip formation, and chip morphology. Model validation is achieved through experimental work carried out under the same conditions as the ones used in modeling. For the experimental work, the principles for design of experiment were used in order to minimize the required amount of experiments and obtain useful results at the same time. Furthermore, a Taguchi analysis is carried out based on the results. The analysis indicates that there is a good agreement between experiment and modeling, and the proposed models can be further employed for the prediction of a range of machining parameters, under similar conditions.</p><p>This article is available on IGI Global’s premier research database, InfoSci-Journals.

The main objective is to simulate both the continuous and segmented chips from the same FE model based on FE code ABAQUS/Explicit. Both the adiabatic and coupled temperature displacement analysis has been performed to simulate the right kind of chip formation. It is observed that adiabatic hypothesis plays a critical role in the simulation of segmented chip formation based on adiabatic shearing. The numerical results dealing with distribution of stress, strain and temperature for segmented and continuous chip formations were compared and found to vary considerably from each other. The simulation results were also compared with other published results; thus validating the developed model.</p><p>This article is available on IGI Global’s premier research database, InfoSci-Journals.

It is extremely difficult to simultaneously maintain a high standard of vehicle ride, handling and body control in the vehicle by using conventional passive suspension system. However, the use of active suspensions would result in better comforts than the passive ones.

A non-linear quarter car model is developed, which includes pneumatic actuation by pressure regulation. The performance of the proposed model was assessed in terms of level of vibration reduction.

For deposition of CPLA, conventional techniques require the surface to be flat, smooth and hydrophilic. In this study, a new method for the deposition of CPLA on a rough surface is proposed and utilized for patterning. In this method, a hexagonal closed pack monolayer of SiO2 spheres was first formed by self-assembly on a flat glass surface. The formed monolayer of particles was picked up by a flexible sticky surface and then placed on the rough surface to be patterned. A Nd:YVO4 laser was used to irradiate the substrate with the laser passing through the sticky plastic and the particles. Experimental investigations have been carried out to determine the properties of the patterns.</p><p>This article is available on IGI Global’s premier research database, InfoSci-Journals.

The proposed technology is easy and does not require specific and expensive equipments. Solid tablets are produced by cold compaction of resin powder, and foam by heating in an oven. Composite foams can be produced by mixing fillers and resin powder before the cold compaction. In the experiment, an epoxy-polyester (EP-PE) resin powder, deriving from the waste of a manufacturer of domestic appliances, was used with montmorillonite (MMT) particles. Resulting foams with a filler content ranging from 0 to 10 wt% were characterized in terms of physical and mechanical properties (by compression tests). Although the effect of the MMT content seems to be negative for the adopted resin, the feasibility of producing composite foams by recycling waste industrial powders is shown. The properties of the unfilled foams are sufficient for many industrial applications.</p><p>This article is available on IGI Global’s premier research database, InfoSci-Journals.

A large number of thermoplastics are available in the market with a variety of properties suitable for different engineering applications, and few of those are available in a not yet polymerised form suitable for resin infusion. The proper selection of a new resin system among these thermoplastic polymers is a concern for manufactures in the current scenario and a special mathematical tool would be beneficial. In this paper, the authors introduce a new decision making tool for resin selection based on significant attributes.

Three coating process parameters are considered viz. bath temperature, reducing agent concentration, and nickel source concentration. It is observed that concentration of reducing agent together with bath temperature play a vital role in controlling the roughness characteristics of the coatings. The analysis yields the optimum coating parameter combination for minimum roughness. A reduction of about 15% is observed in roughness at the optimal condition compared to the initial condition. The microstructure, composition, and the phase content of the coating are also studied with the help of scanning electron microscopes energy dispersive X-ray analysis, and X-ray diffraction analysis, respectively.</p><p>This article is available on IGI Global’s premier research database, InfoSci-Journals.

It is economically and environmentally beneficial to use product recovery methods to divert waste from landfill. The environmental impact of two product recovery methods, remanufacturing and repairing, has been compared via a carbon footprint calculation for a UK-based SME. The calculation has identified that repairing has a lower carbon footprint than remanufacturing, however this only extends the original life-cycle of the product, whereas remanufacturing provides a new life-cycle and warranty, and therefore seen as the most preferable method of product recovery to support sustainable manufacturing.</p><p>This article is available on IGI Global’s premier research database, InfoSci-Journals.

Researchers have used face adjacency graphs and volume decomposition approaches which make the feature recognition complex and give rise to multiple interpretations. The present work recognizes the features in prismatic parts considering Attributed Adjacency Matrix (AAM) for the faces of delta volume that lie on rawstock faces. Conceptually, intermediate shape of the workpiece is treated as rawstock for the next stage and tool approach direction is used to recognize minimum, yet practically feasible, set of feature interpretations. Edge-features like fillets/undercuts and rounded/chamfer edges are also recognized using a new concept of Attributed Connectivity Matrix (ACM). In the first module, STEP AP-203 format of a model is taken as the geometric data input. Datum information is extracted from Geometric Dimension and Tolerance (GD&T) data.

But machining of advanced ceramic like Al2O3-ceramics is very difficult by any well known and common machining processes. Normally, cleavages and triangular fractures generate when machining of these materials is done by traditional machining methods. It is essential to develop an efficient and accurate machining method for processing advanced ceramic materials. For effective machining of Al2O3-ceramics, a traveling wire electrochemical spark machining (TW-ECSM) setup has been developed. The developed TW-ECSM setup has been utilized to machine Al2O3 ceramic materials and subsequently test results are utilized to analyze the machining performance characteristic. Different SEM photographs show the actual condition of the micro machined surfaces. The practical research analysis and test results on the machining of Al2O3 ceramics by developed TWECSM setup will provide a new guideline to the researchers and manufacturing engineers.</p><p>This article is available on IGI Global’s premier research database, InfoSci-Journals.

This new approach of preparing aluminum oxide (Al2O3) nanobricks is based on a soft reaction of aluminum powder and de-ionized (DI) water at 200oC without use of any additives or surfactants. Powder X-ray diffraction studies reveal that the as prepared nanobricks are highly crystalline in nature and by morphological investigations using FESEM, it was revealed that the bricks are rectangular in shape having width of 90±15nm and breadth of ~200nm, which was confirmed by high resolution TEM. The technique could be extended and expanded to provide a general, simple, and convenient strategy for the synthesis of nanostructures of other functional materials with important scientific and technological applications.

The forced vibration analysis is carried out in an indirect way in which the dynamic system is assumed to satisfy the force equilibrium condition at peak excitation amplitude. Large amplitude free vibration analysis of the same system is carried out separately to determine the backbone curves. The mathematical formulation is based on energy principles and the set of governing equations for both forced and free vibration problems derived using Hamilton’s principle. Appropriate sets of coordinate functions are formed by following the two dimensional Gram-Schmidt orthogonalization procedure to satisfy the corresponding boundary conditions of the plate. The problem is solved by employing an iterative direct substitution method with an appropriate relaxation technique and when the system becomes computationally stiff, Broyden’s method is used. The results are furnished as frequency response curves along with the backbone curve in the dimensionless amplitude-frequency plane. Three dimensional operational deflection shape (ODS) plots and contour plots are provided in a few cases.</p><p>This article is available on IGI Global’s premier research database, InfoSci-Journals.

Although it has been a subject of many studies, its full industrial application is not yet established. This article aims to complement the existing research in the area of laser forming in order to gain a better understanding of the process. A numerical investigation of laser forming of stainless steel sheets has been carried out and validated experimentally using a High Power Diode Laser (HPDL). Three processing parameters are tested; laser power, beam diameter and plate thickness. Also, laser bending of stainless steel tube is simulated and compared against the published experimental data. The main underlying mechanisms of laser forming are demonstrated through the simulations.</p><p>This article is available on IGI Global’s premier research database, InfoSci-Journals.

M. Alves (Instituto Superior Tecnico, Portugal), J. G. Medeiros (MC Graça, Portugal), P. A. F. Martins (Instituto Superior Tecnico, Portugal)<br />Volume/Issue: 1/1<br />ISSN: 2156-1680<br />EISSN: 2156-1672<br />DOI: 10.4018/ijmmme.2011010102<br />Date Posted: 1/1/2011 12:00:00 AM</p><p><b><u>Abstract</u></b></p><p>The production of custom and specific tube end shapes by cold end forming using a die is generally limited to seamless tubular parts. Current research work in the field follows the same trend as that of industry and, therefore, there is no accumulated experience, no practical design rules, and no information available in the specialized literature concerning the utilization of tube end forming for shaping the end of thin-walled welded tubes. This paper is concerned with the lack of knowledge and is a contribution towards the understanding of the mechanics of deformation of tube end forming applied to welded tubes. The presentation addresses the influence of major operating parameters on the formability limits of the process with the purpose of understanding feasibility and establishing design rules for the benefit of those who design tubular parts in daily practice. The authors effectively contribute to transferable technological knowledge opening new market opportunities that stimulate innovations among carbon and stainless steel tubular products.</p><p>This article is available on IGI Global’s premier research database, InfoSci-Journals.

Results show the oxide scale thickness decreases significantly with an increase of reduction, and the oxide scales of both 304 and 304L stainless steels were found more deformable than the steel substrate. Surface roughness shows a complicated transfer during the hot rolling process due to the complexity of oxide scale characteristics. Also, surface roughness decreases with an increase of reduction. The friction coefficient increases with reduction in all cases, and the increase is more significant in the case of the 304 stainless steel than that of 304L stainless steel.</p><p>This article is available on IGI Global’s premier research database, InfoSci-Journals.

National Institute of Technology, India)<br />Volume/Issue: 1/1<br />ISSN: 2156-1680<br />EISSN: 2156-1672<br />DOI: 10.4018/ijmmme.2011010104<br />Date Posted: 1/1/2011 12:00:00 AM</p><p><b><u>Abstract</u></b></p><p>Selection of a most appropriate material is a very important task in design process of every product. There is a need for simple, systematic, and logical methods or mathematical tools to guide decision makers in considering a number of selection attributes and their interrelations and in making right decisions. This paper proposes a novel multiple attribute decision making (MADM) method for solving the material selection problem. The method considers the objective weights of importance of the attributes as well as the subjective preferences of the decision maker to decide the integrated weights of importance of the attributes. Furthermore, the method uses fuzzy logic to convert the qualitative attributes into the quantitative attributes. Two examples are presented to illustrate the potential of the proposed method.</p><p>This article is available on IGI Global’s premier research database, InfoSci-Journals.

Andrade-Campos (Universidade de Aveiro, Portugal)<br />Volume/Issue: 1/1<br />ISSN: 2156-1680<br />EISSN: 2156-1672<br />DOI: 10.4018/ijmmme.2011010105<br />Date Posted: 1/1/2011 12:00:00 AM</p><p><b><u>Abstract</u></b></p><p>The use of optimization methods in engineering is increasing. Process and product optimization, inverse problems, shape optimization, and topology optimization are frequent problems both in industry and science communities. In this paper, an optimization framework for engineering inverse problems such as the parameter identification and the shape optimization problems is presented. It inherits the large experience gain in such problems by the SiDoLo code and adds the latest developments in direct search optimization algorithms. User subroutines in Sdl allow the program to be customized for particular applications. Several applications in parameter identification and shape optimization topics using Sdl Lab are presented. The use of commercial and non-commercial (in-house) Finite Element Method codes to evaluate the objective function can be achieved using the interfaces pre-developed in Sdl Lab. The shape optimization problem of the determination of the initial geometry of a blank on a deep drawing square cup problem is analysed and discussed. The main goal of this problem is to determine the optimum shape of the initial blank in order to save latter trimming operations and costs.</p><p>This article is available on IGI Global’s premier research database, InfoSci-Journals.
